UPDATE: Additional arrests have been made in the month-long investigation into illegal bond activity, according to the Tangipahoa Parish Sheriff's Department.

TSD said Wednesday that four more people have been indentified and linked to the crime. Those people have been identified as Shawanda Dove of Independence, Bridgette Harper of Hammond, Ronald Berry of Hammond and Donald Bickham of Hammond.

TSD said that Berry, an inmate of the Tangipahoa Parish Jail, was freed on a $280,000 property surety bond in November. The investigation by the Tangipahoa Sheriff's Office revealed that Berry set up the illegal bond with several others.

According to TSD, Berry's girlfriend, Harper, and her brother, Bickham, sent the payment to Dove who received forged bond paperwork from another party. This led to his release from jail.

Harper and Dove have both been arrested. Police are still looking for Berry and Bickham.

TSD said their charges are conspirary for the illegal consideration of criminal bail bonds, conspiracy to commit forgery, false personation and injuring public records.
